ItsindaAntena y'igihe gito ya Log(LPA) yatanzwe mu 1957 kandi ni ubundi bwoko bwa antene idahinduka inshuro nyinshi.
Ishingiye ku gitekerezo gisa gikurikira: iyo antene ihinduwe hakurikijwe ikintu runaka τ kandi ikaba ingana n'imiterere yayo ya mbere, antene igira imikorere imwe iyo icyo kintu ari f na τf. Hari ubwoko bwinshi bwa antene za log periodic, muri zo harimo Log Dipole Antena (LDPA) yatanzwe mu 1960 ifite imiterere ya bandwidth nini cyane n'imiterere yoroshye, bityo ikaba yarakoreshejwe cyane mu miyoboro ya shortwave, ultra-shortwave na microwave.
Antene ya log periodic isubiramo gusa imiterere y'imirasire n'imiterere ya impedance buri gihe. Ariko, kuri antene ifite imiterere nk'iyo, niba τ itari munsi ya 1 cyane, impinduka z'imiterere yayo mu gihe cy'uruziga rumwe ni nto cyane, bityo ikaba idashingiye ku nshuro.
Hari ubwoko bwinshi bwa antene za log periodic, harimo antene za log periodic dipole na antene za monopole, antene za log periodic resonant V-shaped antene, antene za log periodic spiral, nibindi, muri byo bikunze kugaragara ni antene ya log periodic dipole.
Nk'antene ifite umurambararo munini cyane, uburebure bw'umurambararo ni bugari cyane, kugeza kuri 10:1, kandi bukunze gukoreshwa mu kongera ibimenyetso, gukwirakwiza imbere mu nzu no gukwirakwiza ibimenyetso by'ameza. Byongeye kandi, antene ya logarithmic periodic ishobora no gukoreshwa nk'isoko y'ibikoresho bya antene za micro-reflector. Kubera ko agace gakora neza gagendana n'umurambararo w'imikorere, gutandukana hagati y'agace gakora neza n'icyibandwaho mu murambararo wose w'imikorere bigomba kuba biri mu rugero rwemewe rwo kwihanganira mu gihe cyo gushyiraho.
RF MISO's Model RM-DLPA022-7 ni antene ebyiri zikora kuri polarized log periodic antene zikora kuva kuriKuva kuri 0.2 kugeza kuri 2 GHz, Antene itanga7dBiinyungu isanzwe. Antene ya VSWR ni 2Ubwoko. Imbuga za antene RF ni umuhuza wa N-Female. Antene ishobora gukoreshwa cyane mu gupima EMI, icyerekezo, kugenzura, gupima ubwiyongere bw'antene n'imiterere ndetse n'ahandi hantu hakoreshwa.
RM-DLPA022-7
RF MISO'sIcyitegererezoRM-LPA0033-6 is andika igihe runaka antene ikora kuva kuri0.03 to 3 GHz, Antene itanga 6dBi inyungu isanzwe. Antene ya VSWR ni munsi ya2:1. Antene RF ibyambu niN-Umugoreumuhuza. Antene ishobora gukoreshwa cyane mu gupima EMI, icyerekezo, kugenzura, gupima ubwiyongere bw'antene n'imiterere yayo ndetse no mu zindi nzego zikoreshwa.

RF MISO'sIcyitegererezoRM-LPA054-7 is andika igihe runaka antene ikora kuva kuri0.5 to 4 GHz, Antene itanga 7dBi inyungu isanzwe. Antene ya VSWR ni Ubwoko bwa 1.5. Antene RF ibyambu niN-Umugoreumuhuza. Antene ishobora gukoreshwa cyane mu gupima EMI, icyerekezo, kugenzura, gupima ubwiyongere bw'antene n'imiterere yayo ndetse no mu zindi nzego zikoreshwa.
